CRUSI-IING AND GRINDING MILL;

Specification of Letters Patent No. 12,356, dated February 6, 1855.

To all whom it may concern Be it known that I, J OEL WEIGLE, of SwanStation, in the county of Erie and State of Pennsylvania, have inventeda new and useful Machine for Crushing and Grinding Corn and Cobs and forGrinding Shelled Corn; and I do hereby declare that the following is afull and exact description thereof, reference being had to theaccompanying drawings, making a part of this specification, Figure 1being a top view; Fig. 2, a longitudinal section in the line as 00 ofFig. l; and Figs. 3, 4:, and 5 represent part-s of the machine detached.

Similar letters indicate like parts in all the figures.

The nature of my invention consists in forming a crushing and grindingapparatus by uniting with each other upon the same shaft, the smallerends of two corrugated segments of cones, and combining with themcorrugated inclosing casings supplied with two feeding apertures andarranged in such a manner that corn and cobs can be fed into one openingand be ground intoprovender, and shelled corn be fed into the otheraperture and be converted into meal.

In the accompanying drawings Fig. 3, represents the united corrugatedconical grinders attached to their shaft and detached from the machine.The grinder b, it will be perceived, is larger and has coarsercorrugations than the grinder c. The portion cl, of the casing, whichincloses the grinder b, is secured to the platform k, of the frame ofthe machine in such a manner that it can be moved laterally. This isaccomplished by forming slots in the supporting ears Z, Z, which projectfrom the base of the said casing, for the reception of the screws m, m,which confine the said casing to the platform 70. The casing e, whichincloses the grinder c, is secured to the platform is, by means of theears 7?, p, and the set screws 7, r, as shown in Fig. 1. The casings d,and e, are combined with each other by means of the lateral ears a, n,projecting from the inner end of the former and the ears 2?, t,projecting from the latter, united to each other by screw bolts 8. Theears n, n, have slots in them (as shown in Fig. 5) for the bolts 8, towork in, and which allows the said casing (Z,

to be moved laterally upon the platform is,

for the purpose of producing a wider space between the descending sideof the grinder b, and its casing, than there is between the oppositeside of the grinder and its casing, and to vary the same ascircumstances may require.

Corn and cobs are fed into the machine through the vertical tube 9,which rises from the casing d, opposite the largest end of the grinderI). They are first operated upon between the corrugated surfaces of thegrinder Z), and its casingthe corrugations of which are of such a shapeas to carry forward the stuff operated upon to the small end of thecasing (l, and discharge it into the space between the grinder c, andits casing e, which carry it forward and discharge the same into thedelivery trough d.

When shelled corn is to be ground in my improved mill, it is fed fromthe hopper h, into the receiving aperture f, which opens into the casingd, above the smaller end of the grinder b. When it is desired to grindthe meal finer or coarser, the set screw 12, is turned to vary thedistance between the grinder c, and its casing 6. And when it is desiredto vary the fineness or coarseness of the provender formed of cobs andcorn, in my said mill, the casing 0i, is moved laterally, so as toincrease or diminish the space between the ascending side of the grinderb, and its casing.

Both the corn and cobs and the shelled corn, are first crushed by theaction of the grinder b, and its casing, and are then ground finer bythe action of the grinder c, and its casing e. The corn and cobs passingfrom the largest to the smallest end of the grinder b, and then from thesmallest to the largest end of the grinder 0, get thoroughly ground andincorporated with each other, more so it is believed than in any othermill that has ever been devised.

When it is desired to grind provender coarsely and rapidly, the casingcl, is so-adjusted as to leave equal space on all sides of the grinderb, at the same time that ample space is given (by means of the set screwo,) between the grinder c, and its casing e.

What I claim as my invention and desire to secure by Letters Patent, is

Combining with the crusher b, and the grinder 0, the casings d, e, insuch a manner that the said crusher and grinder can be adjusted in alongitudinal direction, and the casing 03, of the crusher, be adjustedin a lateral direction, substantially in the man- 5 ner and for thepurpose herein set forth.

The above specification of my improved machine for crushing and grindingcorn and cobs and for grinding shelled corn, signed and witnessed this24 day of October A. D.
